6.x feels much more efficient with respect to token usage to be fair.
I picked up superpowers back when it first started gaining traction; the first iteration felt like an “oh shit” moment for me, then the sheen quickly wore off. Higher spend, slower throughput and mediocre results made me eventually drop it and go back to plan mode, which had improved significantly during that time.
Coming back, 6.x does feel different and I’m back on the superpowers train. I’m finding it great at taking discrete tasks from beginning to end with very little hand holding.
I run every session with a /goal as well: “Spec + Plan is written and you have implemented the plan without my involvement. You have validated that the implementation is complete and ready to merge”
It’s also great in situations where you may need to complete a plan over multiple sessions, because you get a whole ton of state with superpowers that new sessions can pickup on.
